a c.f. Additional File 1 for data and Additional file 4 for a summary of sample sizes.

bAverage values except for the measure for expression divergence (Expr-Div), where the value provided should be considered the genome wide proportion of differentially expressed genes.

c Expression Divergence: the percentage of differentially expressed genes between D. melanogaster and D. yakuba.

* and ** indicate significant deviation from the genomic average at P-value ≤ 0.05 and P-value ≤ 0.001, respectively (Chi-square test or two-sided Mann-Whitney test, not corrected for multiple testing).
